Our house has a basement where part of it is finished but one section is closed off by a door and just has a dirt floor. The space is about 25'x25' and about 12' tall (not really a "crawl" space) with a dirt floor. There are about 10 concrete block piers that are about 2'x2' and I suppose that's why the area is unfinished. When opening the door I have to step down about three feet to get to the ground.
The area is dry and I use it to store stuff that I don't use very often (Christmas decorations, tubs, etc). I would like to be more organized and have shelves and such, but the ground is unlevel, has rocks, bricks, concrete, etc and doesn't provide a good place to stack stuff. I would like to install a floor, sorta like a deck but perhaps with plywood rather than planks. My first thought was to just build around the piers, setting posts at each corner. I suppose this would work, but it would be a LOT of hole digging and I suspect I'll hit concrete near the piers. My second thought was to install angle iron around the piers and use it as support for boards as I build around the posts. I'm not too thrilled with that idea either because I have to drill eight holes in each post which doesn't seem like a great idea for support piers. Perhaps that's fine, but I want to hear it from others rather than just assuming.
